Good point about the disallowed loss being with respect to only 7 shares, not 15 shares. That would mean a disallowed loss of $68 per share which doesn't make any sense. To have than much of a loss per share at a sale price of no less than $299 on 3/35/2022 you would had to have purchased shares at at least $367 per share, which is higher than MSFT has ever been.
